I’m definitely not an expert but my dog has similar instances of vomiting, lethargy and runny stool and one thing I know has helped alleviate his symptoms a bit has been a lower fat food. He does better when he is on the Hills ID Low Fat. However, he hates kibble so I struggle. I give him a pouch of Tomlyn Pre and Probiotic powder mixed into some chicken broth and it has helped him. I also give him 14 days of omeprozole antacid at the suggestion of both people on this forum and my vet. If I notice him vomiting I have found the suggestion of slippery elm powder mixed with water and fed via syringe to be really helpful. It seems to ease his acid and calm his stomach. It’s cheap and easy to make. Of course, this is all still pretty new to me so my comment is just what has helped a bit for my sickly little dog. He still struggles a lot but he seems to do better on a lower fat food and especially with the tomlyn pre and probiotic powder I found. That has really helped him. He literally was off it for two days and his symptoms came back. I put him on it again and a day later he is ok. Soooo, seems like that helps a bit. It’s on Amazon for like 17 dollars so not too bad.
Good luck with your pooch. It’s so hard seeing them sick. Hang in there. 🙂
